What is geoscience?

Geoscience (also called Earth Science) is the study of Earth. Geoscience includes so much more than rocks and volcanoes, it studies the processes that form and shape Earth's surface, the natural resources we use, and how water and ecosystems are interconnected. Geoscience uses tools and techniques from other science fields as well, such as chemistry, physics, biology, and math! Read more...

Hard to evaluate the construction of these mega-projects without exploring the counterfactuals. Where should Indians get their electricity from if not hydro power?

Well, in most countries wind and solar are rapidly growing compared to hydro. A more critical question for India is what else could replace the melting Himalayan glaciers and reducing snow cover, as a storage of water for the dry season?

That's more a consequence of hydro sites having been built out already. If you've got a prime candidate for development, you'll find it difficult to get a better yield on the dollar over a smaller geographic footprint.

Water conservation also a very big deal in India right now. Although the downstream impact of damming also tends to be droughts.
